| Abstract: | Conclusions Some properties of anions which affect the extraction of their ionic associates with organic cations have been studied in the present paper. A comparison of these properties is exceedingly difficult even for ions of a single type. Almost any change in the composition of the ion (for example, the substitution of one ligand for another with similar properties: Cl and Br) involves the simultaneous change of the size and effective charge of the ion, the metal-ligand bond stability, and so on. It is not always possible to isolate the factor which has the main influence on the properties of the associate. Besides, the maximum activity of various ions is observed at various acidities in the aqueous phase, and the acidity strongly affects the activity of the dye and its tendency toward association 5]. Nevertheless, the relationships developed herein allow us to interpret the experimental material in several cases and do not exclude the possibility of making predictions for the trends studied.Ural Scientific Research Chemical Institute, Sverdlovsk; Institute of Inorganic Chemistry, Siberian Division, Academy of Sciences, USSR, Novosibirsk.
